we recently broke down a 29 gallon biocube for which i built a diy led fixture. i decided to re-use the diy lighting on this tank. i am going to keep the t5 lights, rework the strip led lights and add the 3w leds in using the dim4 controller. the controller will run the strip leds without an additional driver, so i will have a channel of red, a channel of green, a channel of blue, and the fourth channel will run the driver with the 3 watters. this means i can set it up for a red sunrise and sunset effect with a gradual ramp up/down until the t5 lights kick on/off. i also decided to redo the wooden shells that hold the lights on the top of the tank since they were expanded to house the led strips as they were an afterthought.
on to the pics of what i got done today:
here is what it currently looks like - notice the parts i added on to house the leds
here is the arrangement inside. notice the missing sections on the led strips where they were splashed with water. i will be installing an acrylic splash guard on the new fixtures.
so, today i was able to build the new wooden shells and install the led strips and 3 watt emitters. tomorrow morning i will move the t5s in and wire it all up with the controller.
the one on the top is the back fixture, it has one red strip, one green strip, and two blue strips. the bottom one is the front fixture with one of each color strip and the fifteen 3 watt emitters that are a mix of royal blue and bright blue.
hopefully this will make the top of the tank look a little cleaner and improve the coral colors in the middle of the day when the sunlight is really bright. it will also be cool to use the sunrise/sunset function of the controller.
